Please enlighten me. If she did not believe what she said as literal truth, then what was she trying to say? And why did she not say what she meant? Is it possible that you mean to say her whole speech was an act to communicate a deeper message? A secret message that only pagans understand? Or do you mean to say that this woman had social (or other reasons) to believe this, and she promoted that it didn't matter what she believed because it didn't conflict with her scientific life? Or do you mean that she was encouraging the separation of science and religion by making herself an example of how irrationally stubborn people can be, making it too difficult for science to ever eradicate any false religion because it's "the opium of the people"? Is that what you mean by the "evolutionary function of a creation myth"? How could it play any role in evolution? Were you there during this event, or do you know something I don't?
